Is there a way to make Blade Breaker ships recoverable? I find the effort required to defeat even one of their fleets should at least sometimes be rewarded. By the time you can reliably do that, you are likely fielding high-tech capital ships anyway.
Right, because an entire faction's worth of weird OP sidegrade weapons isn't a reward. You can go into ship_data.csv and delete the UNBOARDABLE tag from their ships.
I'm more likely to add extra rewards via script the way vanilla adds AI Core drops for fighting Remnants. Sigma Matter and Secure Data Storage are also going to get a variety of uses, although I haven't decided exactly what yet.
Awesome update, Soren. I'm impressed with how well you've made the Deserter ships and weapons feel unified and consistent, and the overall level of polish on your content.
I honestly expected to find a single unique derelict to recover for the Bladewood at that location, rather than a BP for it- it feels perhaps a little strange that the Deserter Sparrowhawk is unique but the Bladewood isn't.
The ship itself feels well designed and thought out as an OP-limited, slightly faster and more maneuverable Legion with less direct firepower, but Omni shield and no blind spot. It's strong but doesn't feel like it clearly eclipses any vanilla capital ships, and is fun to fly manually due to the Burn Drive-like system letting it keep up with the fight.
The one thing I find myself wishing for is a Deserter logistics ship that shares their visual patterns and high tech engine trail for fleet consistency, but that's really first world problems. 
Glad you like it. It's very fun to work on; I love making especially rude and flamboyant new weapons.
Right now I just want everything in and I'll polish up the player's access to it over time; the current access to Deserter blueprints of any kind is very much a stopgap implementation. What I'd like to do is make them obtainable via quest chain.
A logistics ship for them would be quick and fun - I'll think about that. The reason the Sparrowhawk isn't obtainable is that it's a jack-of-all-trades design specifically intended for the player; you get some direct firepower, a couple fighter bays, plus Ops Center, all on a highly-mobile platform with good defenses. If it were something you could spam, whole fleets of it would be viable. Ditto the Brave Blade; I might offer a looping mission to replace a destroyed one, but production would require them to be nerfed back down to where they'd be ordinary and less desirable.
